Re: Hydrolic rollers?
if your changing the cam and the lifters are original,then YES,install new ones w/ the new cam. NEVER use old lifters w/ a new cam.
you should also put on new valve springs w/ a new cam.

Re: Hydrolic rollers?
I have to argue that one. Roller lifters don't develop a wear pattern with the cam like flat tappet lifters do. It is perfectly safe to re-use your factory roller lifters with a new roller cam. It's generally a good idea to change springs, as the stockers aren't made to handle much lift and will float fairly easily.
With the older flat-tappet lifters, you DO have to replace them when you change the cam.

Re: Hydrolic rollers?
double agree...roller cams are ground flat,so wear doesnt matter like a hydralic cam.if the roller surface and bearings ok you can reuse them,just clean them up real good,heck take them apart and reclean them,folk rebuild them all the time
